This program will graph a Q-Q Plot of data to visually test for normality. The horizontal axis are the quantiles from a normal probability function, and the vertical axis are the data values contained in list 1.

If the data comes from a normal population, then scatter plot of the data should form a straight line.

The program will overwrite any list in list 5 or list 6.

Be sure to turn off Statistical Plot number three when done viewing the graph.
